So... got the Autotech fuel pump internals and TIP+SRI installed, as well as a new MAF sensor. Buttoned up, primed the pump, and all power was lost when I tried to start it. No lights or anything would come on after repeated attempts. Ended up replacing a blown MAIN fuse in the fuse box, and apparently it was just a symptom of a stripped wire in a harness that was stripped during install at some point, or at some point in the vehicle's past. Anyways, I patched that up with electrical tape.
Now the car pops a P2178 for RICH at off idle. This corresponds with some pretty wonky AFR and Long Term Fuel Trim readings. I am also not pulling as much vacuum as I used to, and discovered that I can only pull around 10 lbs of boost, as opposed to the 15-16 that is normal for this car.
So at this point I am leaning towards a faulty primary o2 sensor, and maybe a bad purge valve. I am also highly suspect of the incredibly beat up HKS blow off valve that I have. The rubber fittings inside of it, as well as the o-ring sealing it to the intercooler are pretty shot. I adjusted and sealed it up as best I could, but now have ordered a new Forge V2 BPV to hopefully solve some of the possible vac/boost leak issues and maybe correct some of the rich issues. Honestly, not sure if that will fix it or not. I am confident that all the clamps and fittings are tight back to the turbo, and the intercooler fittings are likewise tight. I will probably dealer order an o2 sensor this week, maybe that will solve it? Should hear back from my tuner on monday for his suggestions.
